1. Combine the hominy, water, bouillon, onion, garlic, oregano, pepper, and roast (if using) into a large pot and bring to a boil.
2. Meanwhile, prepare the garnish plate. Arrange the cabbage, radishes, avocado, cilantro, lemon, and chips on a large plate.
3. After the soup is boiling, reduce heat to medium and cook for about 10-15 minutes, just letting the onion and garlic soften, and flavors combine.
4. To serve, pour the soup into bowls, bring to the table, and let everyone take want they want from the garnish plate (I recommend a lot of everything), and squeeze lemon juice on top.
Enjoy. The soup is also great without the roast, but if you want a substitute for the traditional shredded pork, it works.
